ABSTRACT:
A leveling system for vehicles including a frame connected to wheels, and a dump body. The dump body is pivotally connected to the frame about a first axis placed at the rear end of the vehicle, and a mechanism for moving the dump body in relation to the frame is provided to enable the dump body to rotate around the first axis for purposes of unloading material inside the dump body. The leveling system includes an inclination detector for detecting the inclination of the first axis relative to horizontal. An adjustment system is provided for adjusting the inclination of the dump body to the horizontal. The adjustment system, itself, includes at least one bracket positioned between the frame and the dump body, wherein the bracket is centrally pivoted on a substantially horizontal pin perpendicular to the first axis. The pin defines a second axis and joins the frame to the dump body. At least two variable extension elements are placed opposite each other on either side of the second axis for connecting the bracket to the frame and adjusting the inclination of the dump body relative to the frame based upon the inclination detected by the first axis inclination detector. The leveling system further includes at least one sensor positioned on part of the motor vehicle for detecting the working position of the vehicle. The adjustment mechanism is activated to adjust the inclination of the first axis relative to horizontal according to the sensed working position of the vehicle.
